I met a unique brothel owner gaining attention on social media. 23-year-old Rika runs a delivery health service entirely on her own. Though she always puts on a cold, gyaru-like attitude, she's surprisingly caring and has a big sister vibe. Her professional demeanor—wearing restraints herself and meticulously serving clients through masochistic play—sets her work apart from ordinary adult entertainment. Why did she choose this path? We conducted an in-depth two-day documentary covering her reasons and daily work routine.
